First let me say that Catholic will be very competitive in 3A. We played them the last 2 years---granted not to competitivley but they are a talented bunch. More importantly they have what seems to be a great coaching staff (and a lot of them).
As for KC tradition I am shaky on that being a factor in their success. I rememebr years ago when NG beat them, and they were not to competitive. It was when they moved the school to west Knoxville and pumped A LOT of $$$$$ into the program that they took off.
As far as recruiting I dont have any first ahnd knowledge, but can offer this, combine first rate facilites, a solid coaching staff, and a chance at a great education-----who needs to recruit the school probably recruits itself.
BTW the Mcfadden kid is legit, could have started for ANY of the Reg. 2 AA powers this year
